RUNTIME ENVIRONMENT
To create the required runtime environment you should choose a runtime library and set
library options. You may also need to override certain library modules with your own
customized versions.
There are two different sets of runtime libraries provided:
● The IAR DLIB Library, which supports ISO/ANSI C and C++. This library also
supports floating-point numbers in IEEE 754 format and it can be configured to
include different levels of support for locale, file descriptors, multibyte characters,
et cetera. (This library is the default for the C++ language).
● The IAR CLIB Library is a light-weight library, which is not fully compliant with
ISO/ANSI C. Neither does it fully support floating-point numbers in IEEE 754
format nor does it support Embedded C++. (This library is used by default for the C
language).
